In 2375, she owned the sixth largest pergium mine in the Sappora system. Yanas did not have a good relationship with her children, especially Ezri, her only daughter. This was due to Yanas' stern and authoritative nature coupled with her domineering behavior. This relationship deteriorated even further when Ezri was joined with the Dax symbiont. With the memories of eight other people, Ezri found it difficult to distinguish herself from the others. When Yanas came to visit her on Trill after being joined, Ezri presented herself to her as Curzon. This convinced Yanas that Ezri should come home, and when she didn't, "things went downhill from there."

Yanas also tried to discourage her youngest son, Norvo, from the arts despite his skills, preferring him to work for the family business instead. After it was revealed that her two sons had been involved with the Orion Syndicate, and that Norvo had killed Morica Bilby, Yanas realized that she was to blame. (DS9: "Prodigal Daughter")
